Title: Generation controller
Inventor: SHINSHI MAMORU
IPC: H02J7/16
Filed: 1985-06-05
Abstract: PURPOSE:To effectively prevent an engine speed from temporarily decreasing or stopping at electric load applying time by altering a set voltage in response to the application of a vehicle electric load. CONSTITUTION:A vehicle generator 1 is rotatably driven by a vehicle engine 3 through a belt 2. A battery 7 is connected with the output side of the generator 1, and the output voltage of the battery 7 is controlled by a reference voltage Vref by a generating voltage controller 8. Electric load groups L1-Ln are inserted in parallel through switches S1-Sn between the output terminals of the battery 7. A generation controller 9 accelerates the rotating speed of the engine 3 in response to the application of the electric loads at idling time. Simultaneously, after the reference voltage Vref is momentarily reduced to the prescribed voltage in response to the application of the loads, the voltage is gradually returned to the set value. Thus, the temporary decrease of the engine speed at load application time can be prevented.

Title: Discharge lamp lighting device
Inventor: YAMADA KOJI
IPC: H05B41/24
Filed: 1992-05-15
Abstract: PURPOSE:To provide a discharge lamp lighting device capable of detecting, when one discharge lamp is removed, this by a detecting part. CONSTITUTION:The voltage E of the DC power source of an inverter circuit part I is set higher than the lamp voltage X2X2<1/2> at the rated current of discharge lamps La1, La2. A detecting part B detects the voltage between positive and negative peak values of lamp voltage of each discharge lamp La1, La2, respectively. Since these detected voltages are smoothed by a capacitor C14 through an OR-circuit formed by diodes D5, D6, the detection output S outputted from the detecting part B is the higher detected voltage. When one discharge lamp La1 or La2 is removed, the DC power source voltage E which is the detected voltage of the detecting circuit on the removed side is outputted as the detection output from the detecting part B, and a control part A detects the detection voltage which is higher than in normal time, thereby stopping or limiting the output of the inverter circuit I.

Title: Condensor for refrigerator
Inventor: NAKAYAMA YOSHIHIKO
IPC: F25B39/04
Filed: 1977-10-14
Abstract: PURPOSE: To maintain a proper condensation pressure by the arrangement such that almost all heat-conducting pipes operate condensation when the coolant liquid is at high temperature and some of the heat-conducting pipes are immersed in the refrigerent liquid when the coolant liquid is at low temperature.  
     CONSTITUTION: When the coolant liquid flowing heat-conducting pipes 2b is at high temperature, since valve 18 is open, refrigerent liquid 19 is supplied to evaporator 4 via valve 18 and exit pipe 13 and almost all heat conducting pipes 2b operate condensation without being immersed in refrigerent liquid 19. In the case where the coolant flowing in heat-conducting pipes 2b is at an extremely low temperature, since valve 18 is totally closed, refrigerent liquid 19 is stored at the bottom of shell 2a and about half the group of heat-conducting pipes 2b are immersed and thus the heat conducting area to operate condensation is reduced, and thereby a proper condensation pressure is maintained. Although condensation head is increased, since the amount of refrigerent liquid circulation is reduced due to over-cooling, there is no change in the cycle efficiency

Title: Discharge valve
Inventor: WATANABE KIYUUHEI
IPC: F16K1/12
Filed: 1978-10-06
Abstract: PURPOSE: To seal water uniformly and positively while decreasing the capacity of a servo-motor, by obtaining water sealing force by working the pressure of water currents to seal portion material connecting portions when closing this valve.  
     CONSTITUTION: When closing this valve, a cylinder gate 15 is moved up to a discharge opening end portion by means of a servo-motor, and a connecting surface 18A of the seal ring 18 and a connecting surface 17A of a seat ring 17 of a discharge body 12 are contacted. A pressure receiving surface 18B at the water current opposite side is subject to pressure by water currents in the seal ring 18, the connecting surfaces 17A, 18A are sticked fast by the push force and water seal is formed. In this case, precise watertightness is obtained because water pressure uniformly acts on the pressure receiving surface 18B made up along the whole circumference of the seal ring 18. Deflection to the seat ring 17 side increases in the seat ring 18 when the ring 18 receives pressure owing to a round hole 18C built up at the water current opposite side, and water sealing action becomes more conspicuous.

Abstract: PURPOSE:To maintain the top speed and make the number of inverters minimum at conveyers driven by means of a single power source at a place such as a factory or the like, by arranging so that acceleration may be regulated by feeding electricity through a single inverter at the times of start up and fall down of conveyers, and electricity may be fed directly from the power source at the time of a regular operation. CONSTITUTION:At the time of the start of conveyers, changeover devices S1-Sn are changed over to b, and electricity from a three phase alternating current power source 1 is supplied via the route b through an inverter 2, and acceleration is adjusted by means of the inverter 2, and each conveyer is started one by one. That is, changeover devices S2-Sn are made OFF, and the changeover device S1 alone is made b, and the opposing conveyer is started by means of a motor M1. And when a regular condition is brought in, the changeover device S1 is changed over to a, and the changeover device S2 is likewise, operated. Those that follow make repetition in turn. Braking also is done one by one by means of a brake 3. As a result, the number of inverters can be minimized.

Title: Catalytic combustion device
Inventor: MATSUI YASUTSUGU
IPC: F23N5/12
Filed: 1982-07-14
Abstract: PURPOSE:To equalize the temperature distribution through catalyst bodies by a method wherein the outer wall surface of each of the tubular catalyst bodies having an oxidized catalyst adhered to the inner wall surface thereof is cooled by a premixture of a fuel and air. CONSTITUTION:Combustion gas flows in the direction of arrows and heats tubular catalyst bodies 14. When a detector 12 detects that the catalyst bodies 14 are preheated to a predetermined temperature, a changeover valve 11 closes once and the flames on a multipipe type burner 7 are extinguished. Then, after a flame detector 10 ascertains that the flames are completely extinguished and when the changeover valve 11 is opened and the fuel is supplied, the fuel is mixed with air supplied from a blower 1 to become the premixed gas and the premixed gas reacts within the tubular catalyst bodies 14 to initiate catalytic combustion. Consequently, since the catalyst bodies 14 are cooled by the premixed gas, the temperature of each of the catalyst bodies does not change radically even when the air-fuel ratio and the amount of combustion vary.
